  how many times larger the image is compared to it's actual size
• how would u calculate magnification ?

  image size divided by object size
• how to calculate the object size?

• how to calculate the image size of an object ?

  object size x magnification
• what is the definition for resolution ?

  the shortest distance in which an object can be apart without appearing blurred
